CPEX-CV Dropsonde Data: Atmospheric Profiles from Cabo Verde Campaign

Dropsonde data files collected during NASA's Convective Processes Experiment - Cabo Verde (CPEX-CV) campaign in September 2022. The campaign operated from Sal Island, Cabo Verde, deploying instruments on a DC-8 aircraft to measure tropospheric aerosols, winds, temperature, water vapor, and precipitation. The data collection is complete and aims to improve understanding of atmospheric dynamics, convection, and the Saharan Air Layer in the tropical East Atlantic.

Use Cases

• Analyze vertical profiles of atmospheric winds based on dropsonde measurements.
• Study the thermodynamic structure of the marine boundary layer based on temperature and water vapor data.
• Investigate Saharan dust transport pathways based on aerosol and wind observations.
• Validate and interpret spaceborne remote sensors based on coordinated airborne measurements.
• Improve prediction models for tropical Atlantic weather systems based on in-situ atmospheric observations.

Strengths

• Data collection is complete, indicating a finalized dataset.
• Campaign operated from a specific location (Sal Island, Cabo Verde) over a defined period (1-30 September 2022).
• Data is collected by a major scientific organization (NASA).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats include BIN and ISO, which may require specialized tools for access.
